[Reversible functional shutdown of the optic tract on exposure to focused ultrasound]

The possibility of reversible functional blockade of the optical tract and blockade of optical information conduction has been shown by means of undestructive doses of focused ultrasound. Electron microscopy of optic terminals in the superior colliculus in the period of restitution of the bioelectric activity of the optical tract has demonstrated that alterations in the ultrastructure of optic terminals were insignificant and reversible.
